Yes. CARB allows a temporary 5-Day Pass for trucks entering California without a Clean Truck Check certificate. This permit lets out-of-state or newly purchased vehicles operate legally for up to five days while arranging emissions testing or registration compliance.

Beginning in 2025, more vehicles, including out-of-state trucks operating in California must report test results and maintain compliance. Non-compliant vehicles may face registration holds or fines.

To receive a valid Clean Truck Check certificate, your vehicle must undergo the required Periodic Emissions Assessment (PEA) at a CARB-approved testing facility. Once your vehicle passes, the testing facility electronically submits the results to the Clean Truck Check program and your certificate is issued. Vehicle owners do not need to submit the test results themselves.
